CROSS-REFERENCE TO RELATED APPLICATIONS

This Application claims priority of Taiwan Patent Application No. 101114614, filed on Apr. 25, 2012, the entirety of which is incorporated by reference herein.

FIELD OF THE INVENTION

This invention relates to a real and virtual identity verification circuit, a system comprising the same and an electronic transaction method, capable of carrying out electronic identity verification with high security in a virtual environment on the Internet through the use of a user's unique biological characteristic in a real environment.

BACKGROUND OF THE INVENTION

Recently, with the growing popularity of the virtual environment established by the Internet and its penetration into the real environment of consumers, new lifestyles appear rapidly and change people's consumption habits. For example, instead of doing shopping in a real store, more and more consumers choose to make online transaction in the virtual environment, such as a shopping platform built on the Internet.

There are several reasons why virtual stores gradually replace real ones and grasp a substantial share of the market. In contrast to real stores, the virtual environment provides a low-cost sales channel to reduce considerable real store costs and personnel costs. In addition, the virtual environment provides consumers with much more flexibility, allowing them to do shopping anytime and anywhere.

However, the most important issue for consumption in the virtual environment is how to determine of consumer's identity in the real environment. Apparently, consumer's identity can be confirmed by a real identity certificate or proof of identity; however, in the virtual environment, documents are prone to alteration since they are available only in the electronic form. Accordingly, it is desirable to verify the identity of a consumer in a highly secure way in the virtual environment.

To address the above-identified problem, many solutions have been proposed. For example, consumers may first create an account representing their identity and a set of password for the account, such that they can perform operations in the virtual environment with the account and the password, such as performing electronic transaction with a credit card and the account as well as the password. Nevertheless, security may be jeopardized if the account and the password or even the credit card is hacked. Another approach is to electronically verify an identity document, which is mostly used by the government agencies. For example, a certification IC card is issued upon application by a household registration office according to the applicant's unique identity, and the certification IC card may be used to represent the holder's identity. Although the electronic identity system established by the government is authoritative and reliable, the verification process may still be damaged because it uses fixed passwords. In addition, in order to maintain its security, the system adopts a closed design mostly limited to government purposes and is rarely opened to the private sector.

Furthermore, some commodities, such as lottery tickets, are not currently suitable for consumption by electronic transaction. Lottery tickets are un-inscribed value-bearing instruments, so the one who holds a lottery ticket is deemed to be its owner. Thus, the purchase of lottery tickets usually has to be done by consumers in person, making lottery transaction quite inconvenient.

Accordingly, the present invention provides a real and virtual identity verification circuit, a system comprising the same and an electronic transaction method to address the drawbacks mentioned above.
